Please report this via http://www.gnu.org/software/gcc/bugs.html. Your 
bug report is short and precise, and will be appreciated.

Just FYI, this seems to be a problem with the .stabs entry for the 
register variable "a".

That's because the bug is (likely) related to generating COFF stabs 
(Linux uses the ELF file format, and the DWARF debugging information 
format, which may explain why it's not affected). Chances are any other 
platform with the same combo of object file and debug formats will show 
the same bug, though it's not a slam dunk.
